elm-format (0.2.0-alpha)

[Aaron VonderHaar]

After the tedious work of making the AST retain comments, elm-format-0.2-alpha is ready! Most notable is the switch to 2-space indentation, as previously discussed on elm-dev. There are also now plugins for LightTable, Emacs, and Vim thanks to @rundis, @Bogdanp, and @ajhager!

You can find the downloads and editor integration instructions here:

• https://github.com/avh4/elm-format
• https://github.com/avh4/elm-format#basic-usage

Here's a brief list of changes:

• changed to 2-space indentation
• comments are handled everywhere they can appear
• fixed a unicode problem with console output on Windows
• parentheses in pattern matches are handled correctly, including a workaround for elm-lang/elm-compiler#951
• triple double quotes in multiline strings are handled correctly
• more than one file or directory can be given on the command line
• added the --stdin command line option to support IDE plugins

Thanks to everyone who helped improve the documentation and to the following for contributing code to this release:

• Martin (@Janiczek)
• Marica (@ento)
• Janis (@jvoigtlaender)
• and to several others who helped improve the documentation

Wooo!!! Thanks to Aaron and all the contributors. This is already one of those tools that I never want to live without again. Really just superlative. :)

Wow, great work! It sounds like you've fixed all the major issues from last time!

Is there a complete description of the style anywhere? I'm currently working on a fork of hindent to try to match the style of Haskell code to the Elm guide, but I'm wondering which corner cases I've missed.

Joey, what kind of description are you looking for?

There is an almost complete test suite here: https://github.com/avh4/elm-format/tree/master/tests/test-files/good/AllSyntax  (which is currently a bit disorganized).  All files in there are correctly formatted.

You might take a look at the main implementation file: https://github.com/avh4/elm-format/blob/master/src/ElmFormat/Render/Box.hs  It's long, but I think it's pretty well organized.  There are functions and cases for all parts of the AST.

Fantastic!! Thank you, all!

[Joey Eremondi]

@Aaron thanks, I'll take a look at those, they probably have what I want!

I was thinking something like this, but that was actually complete, there's a lot of missing cases. But it probably donsn't make sense to have a textual description of the entire guide.
